Gannen is a morning seafood restaurant near Nijo Market in Sapporo that serves seafood rice bowls and grilled fish set meals. Its main dishes are grilled atka mackerel and kaisen don, and the rice in the bowl can be ordered as plain rice or sushi rice. It opens at 8 a.m., and lining up from around 7:30 can mean a wait of 20 to 50 minutes. The interior seats about 14 to 16 people, so it is cramped for larger customers, and showing a photo makes ordering easier.
